We are all cloud and remote. We deploy and enroll devices through Intune Autopilot. We have a user whose device is spiking CPU usage. I am not too familiar with hardware, and I would like some advice/direction on how to see what is causing the problem and how to troubleshoot. I downloaded the diagnostics but I am not sure what to look for. The device was deployed in 2022. Is it just old?
Here are the specs:

Operating System

Operating system: Windows

Operating system version: 10.0.19045.6332

Operating system language: en-US

Operating system edition: Enterprise

Operating system SKU: Windows 10/11 Enterprise (4)​

Storage:

Total storage space: 237.31 GB

Free storage space: 70.45 GB

Total physical memory: 8.00 GB

    Hello Brianda Sanchez,

    Few quick checks for performance troubleshooting,

    1. Perfmon is the more straight forward way. If you have them collected, some key counters to check are Processor, Process, Memory, PhysicalDisk. This helps identify the top consumers and bottlenecks.
    2. Resource Monitor(resmon): This gives a GUI view of which processes consume more CPU and memory.
    3. Clean boot: Disable all third-party services and reboot to check if there is improvement (msconfig ->Services -> Hide all Microsoft Services -> Disable). If yes, isolate and figure out which service is causing the spike.

    Additionally, make sure Defender or your AV is not running a full scan when there is a spike, try repairing system files (sfc /scannow) and check storage health(chkdsk /scan).

    Hope this helps!
